To all whom. it may concern:

Be it known that I, GUsTAvE ANDREEN, a resident of Omaha, in the countyof Douglas and State of Nebraska, have invented certain new and usefulImprovements in Fire-Proof Doors or Shutters, of which the following ishereby declared to be a full, clear, and exact description, sufficientto enable others skilled in the art to which said improvements relate tomake and use the same.

. The invention relates to that class of heavy shutters or doorsarranged to slide in front of Windows or other openings, and which aremade of iron or other fire-proof material for protection against fire.

The invention has for its object to provide means whereby the shutter ordoor may be shifted in position along the rail, either back or forth, bymeans of the hose-stream directed against the same.

In the accompanying drawings, Figure 1 shows an outside view of ashutter or door made in accordance with the invention. Fig. 2 is asectional view thereof. 4

Each leaf or section of the door or shutter D is furnished with suitablehangers E, carrying rollers e, which travel upon the horizontal rail B,secured above the opening to be covered, .and the lower portion of thedoor will be guided by a suitable bottom rail B, in manner Wellunderstood. Upon the front or outer face of each section D of theshutter or door is fixed a striker-plate A, that rises preferably from abase-plate a, secured to the door-section, this base-plate beingconveniently extended at its top, as at a, so as to Serial No. 316,217.(No model.)

The combination, with the supporting rail and with the door orshutter mounted to slide thereon, of the strikenplate projecting fromsaid shutter or door and having an overhang at its top to form a pocketor cavity against which a hose-stream may be directed to shift the dooror shutter, substantially as described.
